Columbia University has barred several individuals accused of spraying pro-Palestine protesters with a foul-smelling chemical during a demonstration, the New York-based institution has said.

“The University received additional information Sunday night. As a result, the alleged perpetrators identified to the University were immediately banned from campus while the law enforcement investigation proceeds,” Mitchell wrote, according to the US media outlet Rolling Stone.
Mitchell said the university condemned “in the strongest possible terms any threats or acts of violence” directed towards its community and described the incident as “deeply troubling”.
Columbia has asked anyone in possession of photos, videos or any other evidence of the event to present it to the police department.
The university did not clarify whether those banned were students, or how many individuals were involved.
